HIDE AND OTHER MATERIAL \VORKING MACHINE.

Specification of Letters Patent.

Patented Mar. 1, 1910.

Application filed June 19, 1908. Serial No. 489,395.

To all whom it may concern:

Be it known that We, EUGENE A. Fisi-mn, a subject of the German Emperor,and JOSEPH W. STEINIIAUSER, a citizen of the United States, bothresidents of Bethel, in the county of WVindsor and State of Vermont,have invented certain new and useful Improvements in Hide and otherMaterial l/Vorking Machines, of which the following is a specification.

Our invention relates to machines in which a rotary roll is employed towork upon material for the purpose of cleansing, cutting, grinding,polishing or otherwise treating the same, for example buffing leather,and its object is to provide means for cleansing said work roll withoutstopping its rotation, also means for protecting such material from thedraft caused by fans so often employed in these machines to carry 01fthe matter removed from the material.

It is illustrated by the accompanying drawings in which- Figure 1 is aside elevation of the machine. Fig. 2 is a front elevation with thepulleys omitted. Figs. 3 and 1 are detail views of certain portions ofthe machine.

Similar characters refer to similar parts throughout the severaldrawings.

The parts are mounted upon the frame 1. The work roll 2 is mounted uponthe shaft 3 journaled in the frame, to the end of which shaft is fixedthe pulley 1. The bed (feed) roll 5 is mounted upon the shaft 6journaled in the swinging arms 7 mounted upon the shaft 8 fixed to theframe and having their lower ends pivoted at 9 to longitudinallyadjustable rods 10 slidingly mounted in the upper ends of the bell cranklevers 11 fulcrumed on the shaft 12 fixed to the frame and supporting ontheir lower ends the treadle 13. These adjustable sliding rods 10 arefurnished on their inner ends with adjustable nuts 14 which engage theupper inner ends of the bell crank levers and are furnished on theirouter ends with spring adjusting nuts 15 and lock nuts 16. The springs17 are adjustably mounted upon these rods between the nuts 15 and theupper outer ends of the bell crank levers. The frames 18 areosoillatively and slidingly mounted upon the shaft 19 fixed to the frameand are pivoted at 20 to the swinging arms 7 and they include chambers21 through which run the plunger rods 22, whose enlarged inner ends areadapted to contact with the frame 1 and on whose reduced outer portionsare disposed the springs 23. The outer ends of these springs abutagainst the walls of the chamber and the inner ends abut against theenlarged portion of the plunger rods. The pins 21 hold the frames on theplungers. The inward movement of the frames is limited by the adjustableset screws 25, which are held in adjustment by the nuts 26. The hood 27is mounted upon the frame 1 and within this hood is arranged a fan (notshown) upon the fan shaft 28 journaled in the frame, to the end of whichshaft is fixed the pulley 29. \Vithin the hood 27 is also arranged therotary brush 30 whose shaft 31 is mounted in the free ends of theswinging arms 32 pivoted to the frame at 33 and pivoted at 31 to theforked link 3.), which, in turn, is pivoted at 313 to the treadlc 37fulcrumed on the shaft 38 fixed to the frame. The gate 39 is fixed tothe shaft -i1-() rotatably mounted in the frame and is locked in avertical position by the pins 411 extending through the frame and intothe gate. The object of the hood and fan is to provide for the disposalby suction or draft of the waste material, and the object of the gate isto prevent the material worked upon from being drawn into the hood. Thegate is hinged to provide easy access to the interior of the hood andmore particularly to the brush mounted therein. The pulleys 1-2 and 413are fixed on the main driving shaft. 4-1- and are connected by belts 4-5and -16 respectively with the work roll shaft and the fan shaft.

The operation is as follows: lower being applied, the work roll and thefan roll rotate in the direction shown by the arrows, the bed (feed)roll and the brush roll being at rest as shown in Fig. l. The operatorplaces the material to be treated over the bed roll and depresses thetreadle 13 thereby bringing the bed roll into contact with the workroll, he having first secured the desired pressure, for example livepounds or ten pounds, between the bed roll and work roll by adjustingthe springs 17 upon the sliding rods 10. springs 28 are compressed inthe chambers 21 (Fig. 1) and, when the operator removes his foot fromsaid treadle, these springs re turn the bed roll to its normal position.The

operator, whenever he desires to clean the At the same time the workroll, depresses the treadle 37, thereby bringing the brush 30 intocont-act with said work roll, the brush being returned by gravity, whenthe operators foot is removed from the treadle. The material, as it isoperated upon, drops down in front of the gate 39 and is preventedthereby from being drawn into the hood.

The features of our invention are as follows: FirstMeans for cleaningthe Work roll without stopping the machine. Second Protecting thematerial operated on from being drawn into the hood by the draft createdby the fan. ThirdProviding easy access to the hood and brush disposedtherein. FourthAdjusting the pressure between the bed (feed) roll andwork roll. Fifth-Counterbalancing the bed (feed) roll.

In the operations mentioned, and similar operations, it is customary tocover the work roll with material adapted to perform the desiredwork-for example, for buffing leather the work roll is covered withemery paper or cloth. Heretofore, in order to clean these coverings ithas been necessary to stop the machine and remove them from the workroll, which results in the loss of much time and in the speedydestruction of such coverings. We avoid these difliculties by the meansdescribed, which provide for a speedy and economical cleaning of thework roll or its covering as frequently as may be desired, withoutstopping the machine.

Having described our invent-i011 what we claim and desire to secure byLetters Patent is 1. In a machine of the character described, a frame; awork roll mounted thereon; a work-supporting roll mounted on said frameand movable to and away from said work roll; and a brush roll forperiodically cleaning said work roll and movable to and away from it;with means for accomplishing said movements; sub stantially asdescribed.

2. In a machine of the character described, a frame; a work roll mountedthereon; a work-supporting roll mounted on said frame; and a brush rollfor period ically cleaning said work roll and movable to and away fromit; with means for accomplishing said movements; substantially asdescribed.

3. In a machine of the character described, a frame; a Work roll mountedthereon; a work-supporting roll mounted on said frame and movable to andaway from said work roll; and a brush roll for periodically cleaningsaid work roll and movable to and away from it; with treadle mechanismfor accomplishing said movements; substantially as described.

4. In a machine of the character described, a frame; a work' rollmounted thereon; a work-supporting roll mounted on said frame; and abrush roll for periodically cleaning said work roll and movable to andaway from it; with treadle mechanism for accomplishing said movements;substantially as described.

In a machine of the character de scribed, a frame; a work rollmounted thereon; and a bed roll mounted in swinging arms journaled insaid frame and movable to and away from said work roll; with means formoving said bed roll to said work roll; and means for moving said bedroll away from said work roll; said last-named means comprisingspring-controlled frames oscillatively and slidingly mounted in saidfirst-named frame'and pivoted to said swinging arms; with controllingsprings; substantially as described.

8. In a machine of the character described, a frame; a work roll mountedthereon; and a bed roll mounted in swinging arms journaled in said frameand movable to and away from said work roll; with means for moving saidbed roll to said work roll; and
